CROP SCENE INVESTIGATION – 38: What’s behind the weed escape in Scott’s soybeans? – SOLVED

by BERNARD TOBIN

Weed resistance was the cause of Scott’s foxtail escapes featured in our March 2012 issue. What agronomist Pat Lynch found in his field was Group 2 resistant foxtail.

The clue to the mystery was contained in the dead and dying weeds that could be found beside the green, vigorous foxtail plants.  A close look revealed that many foxtail plants had turned red and purple and were dying – the classic death symptoms of foxtail that are not resistant to Group 2 graminicides.

CROP SCENE INVESTIGATION – 37: What caused the yellow spots in that winter wheat? – SOLVED

The yellow spots identified in wheat fields last spring by Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) cereals specialist Peter Johnson were caused by sulphur deficiency.
Tissue sampling revealed that green, healthier plants in other areas of the field tested much higher for sulphur levels than the yellow plants. The diagnosis was confirmed when Johnson applied sulphur to test strips of yellow plants.

The patent has expired on the original Roundup Ready soybean seed, launched by Monsanto 15 years ago, and growers are free to buy it in 2012 and save it for next year. The tricky part might be finding a company that will sell you that seed.

“Most have transitioned to Roundup Ready 2 because that is what growers want,” says Trish Jordan, spokesperson for Monsanto Canada, which won’t be selling Roundup Ready 1 anymore.

Every spring, Peter Johnson sees yellow spots. It’s just one of those things that happens in winter wheat, says the Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) cereals specialist.

The reason for those lighter-coloured areas in wheat fields is almost always manganese deficiency, particularly on sandy soils, muck soils and high organic matter soils. But, in 2011, many of the spots left Johnson scratching his head, searching for an explanation.

Jerusalem artichokes and empress trees – new crops with potential

Though they are barely at the starting gate in Ontario, both show promise if market demand for biofuels continues to grow. But both also need processors to get them off the ground

Larry Whetstone’s business is selling inulin, a type of sugar derived from chicory crops in Europe, but he’d rather be selling inulin produced from Jerusalem artichoke crops in North America.
